1. Define 'Crashing'. Is it the 'non-responding' message, is it frozen and does the mouse cursor not move anymore, does it quit PR and checking for a solution, is it turning off your machine, is it a BSOD?

2. Are you using the latest video drivers from nVidia? Current version is 296.10

Have you already tuned your system a bit? Removing games, MSN and similar crap, disabling the sidebar permanently, turning off indexing and compression of both drives, setup a fixed pagefile on the D: drive, etc.?

It could be a compatibility issue between the i7-3930K and the RAM. Read posts from Scott Chichelli about the i7-3930K and you'll find that that CPU really needs 1.35V-rated RAM to work correctly, and that there is a major issue between the 3930K's memory controller and the Micron chips that are used on most RAM modules these days.

The even more expensive i7-3960X's memory controller does not suffer from the same issue.

1. I probably should have said "freezing". The on screen image is frozen...I cant move the mouse, work the keyboard, CNTL+ALT+DEL is no use. I have to shut the PC down manually (hold PWR button on case down for 3-5 secs).

2. Nvidia drivers are up to date, I downloaded the driver about 2 weeks ago. I'll double check this when I get home.

3. The only "tuning" I've done, is disabling windows indexing. As far as the the other suggestions go, "removing games, MSN and similar crap, disabling the sidebar permanently, setup a fixed pagefile on the D: drive, ect"...I had no idea that these would help. Do you have a link or a list of programs/operations that need to be addressed? I don't even know what a "fixed page file on the D:" is

This "freezing" that you describe occurs with both Gigabyte and Asus boards with early versions of the BIOS. Update your BIOS to the latest version - the problem was solved in BIOS releases in early March.

This cured the problem on my Gigabyte motherboard, and I know of one other user with an Asus board who took this advice and solved the problem.

It sounds as though the BIOS update may well have solved your freezing problem - your description of the problem sounded just like my very similar system with the original BIOS.

I have built a system very like yours, except that I am using a Gigabyte GA-X79-UD5 motherboard and two RAID0 arrays, plus two single drives for storage.

As for memory being the problem, I am using 32 GB of Corsair XMS3 PC£-12800 at 1.5V and since the BIOS update my system has been 100% stable. So unless the problem that Scott alleges exists is confined to Asus motherboards, I doubt that your problem lies with memory.

So I've done a fair amount of "tuning". Went through and turned off some of the windows features I wont be using. Also went over to Black Viper and adjusted my setting based on his "safe" configuration.

The problem with the ghosting text boxes was solved with: Control Panel-->System-->Advanced system settings-->Visual Effects-->Adjust for best performance! Looks a bit bland, but I'll get use to it.

No crashing or freezing yet!

I am, however, still having trouble with scrubing video (when I grab the little blue triangle in PP and move it back and forth). It does it when the footage has a YELLOW bar over the top. With a GREEN bar, everything scrubs smoothly. Any suggestions or something I'mmissing?

There is a reason the turning off the Aero seemed to solve your ghosting and other video anomalies. When the Aero is on then Windows controls the Memory managment for the video/display. This also means there is allot more caching to ram to handle the frame buffer isolation. When people have pointed you to ram they were not incorrect on this. The MPE engine uses the system ram for the grand central station of data transiting between the CPU, video cards, and storage. If the timings on the ram are not syncing correctly to the ram controller in the cpu then your going to have random anomalies including drawing out on the screen because all of that data is transiting through ram as well. Think of it this way. If the memory controller sends a read request to a page on the ram that was prematurely wiped or not refreshed in time, then that data is garbage regardless of the rest of the data. You can manually set bios settings to try and get that ram to work or you can look at ram meant for that platform. BTW so everyone is aware, It seems Samsung has transitioned to 1.35V ram for their modules available in retail atleast from what I can see available in stock. That is tvery telling if they have done that since 1.35V requires better grade chips which raises the price of production.

Thanks for the info! I grasped some of what you explained (I'm not a computer guy....although, this build has tought me alot!).

I tried the Samsung memory linked above, but it did nothing for the ghosting text. Turing off some of the features in windows fixed that, but brought about another problem....the horizontal lines in video playback. I turned Aero ON (in a limited capacity) and it seemed to have solved the horizontal line issue...weird .

Could you recommend any other 1.35V memory that is meant for this platform?

Concerns about sluggishness on the time-line, involving scrubbing and random brief playback and trims, have been raised here before by newer users..... What kind of responsiveness is to be expected, with a x79-based system like this one?

We have not had the Samsung 1.35V ram in stock here to test yet. I am still trying to get 8 modules here so we can verify compatibility and settings. However based on the rated timings I expect they should work fine if the bios is setup correctly. I need to know your current bios settings with those in. You can email me directly at support@adkvideoediting.com or call at your convenience. Number is on the website.

Eric, in reply to your post (#10), what makes you assume that I did not discover this information for my Gigabyte motherboard before upgrading my BIOS? I admit that it was an assumption on my part that Asus motherboards would have the same solution, but I know of another user who solved this probem with his Asus motherboard by upgrading the BIOS to 1010.

The rest of your response to me is irrelevant - my system functions correctly and does not, and has not in the past suffered from these problems.

The post was to reference why it worked for you and possibly other users. I did not assume anything beyond what you stated to the original post which was that memory was likely not the issue. I was pointing out the bios update was based around memory comparability. Now what you set your ram and bios settings to after the update I dont know. If those settings are default since most of the bios updates default the CMOS then that would also explain why it's working as well. The importance of the post was to get the original person back on track to what is causing the issue they are having and why. In that process I had to explain why a bios update might fix something similar to their issue and the reason for that. The rest of the response was toward the original person.

In post 14, I said that the problem was not his memory because he had updated the BIOS by then (as I suggested in post 11), and that solved the memory compatibility problem.

The rest of your post 27 was directed at me too, it was headed as a response to a post of mine. If you wish to respond to two posts at the same time, it would make sense to use separate responses to avoid confusion.

I am using the 3930K processor, which had this memory compatibility problem, which as I said originally, was solved by Gigabyte and Asus in BIOS releases in early March.

The processor is not overclocked.

Please do not think that I am attacking either ADK, or its personnel.

I was simply trying to correct the misconception contained in this thread that this memory incompatibility is a current problem. It is no longer a problem, at least for a non-overclocked 3930K, provided the BIOS is updated. This is evidenced by the OP stating that once he had updated the BIOS, the freezing ceased.

I apologize for the confusion with posting to 2 posts in the same post. I normally try to avoid double posting unless it's a follow up thought.

Actually the blanket memory compatibility fix is another point I was trying to dispel. Just because the fix worked for your modules does not mean it's going to work for everyone else. The changes alone between Corsair XMS modules between batches and runs is significant depending on what their building with when and binning. Now multiply that by each model/series and then each manufacturer. There is no way Gigabyte or Asus can update timing detection and round trip latency adjustments for every one of those in a single update. It likely may have just fixed a few batches of any one manufacturer and only at certain speeds if that much. Once again there are to many variables to assume it's a blanket fix for memory compatibility and I dont want people lead down the wrong path in troubleshooting these because of that.

The system not freezing is not the only symptom the poster stated that is a sign of ram issues nor is that the only symptom of the ram issues. Ghosting is a frame buffer corruption issue. Now the question is where the frame buffer corruption is occurring. Is it on the video card or the system ram. Considering the Ghosting went away when the client turned off the aero then the answer is the system ram. When the Aero is turned off, then the video driver alone handles the memory management which uses less ram. Also the anomalies on preview with lines with the MPE engine is also due to a corrupted frame buffer. So yes the memory is still an issue and the assumption it's not is completely incorrect.
